T a/ZZ whom Lt may coaccrn:

Be it known that I, Jimrns A. KnNwonTI-rr, a citizen of the UnitedStates, residing at Oakland, in the county of Alaineda and .State ofCalifornia, have invented new and useful linproveinents in Carbureters,of which the following is a specii'ication.

rl`he present invention relates to an improved apparatus for producingilluminating and fuel earbureted air from volatile oil, such asgasolene, distillate, and the like.

rl``he object of the invention is to produce an apparatus of thischaracter which is comparatively cheap and simple in construction, whichmay be readily moved from place to place where needed, which willfurnish a large amount of gas in proportion to its size, with which thecare and attention required may be reduced to a minimum.

ln the aecompanying drawing, Figure 1 is a vertical section of myimproved apparatus; lFig. Q is a detail view of the trippingniechanisin.

The apparatus comprises ay carbureter, in which the air is carbureled byforcing it through gasolene or other oil, which is also Constructed toform a receiver for storing the air thus earbureted, and a pump forobtaining the necessary air pressure for so forcing the air through theoil.

Referring to the drawing, 1 indicates the bottom of a carbureter casingupon which are erected inner and outer cylindrical walls 2, 3, foriningan annular water chamber Al. is the cylindrical wall of a bell orreceiver, depending into said annular space Lt and closed by a top 0. Onthe outer wall 3 are securer guide rods 7, and on the top of the bellare Secured guides 8 which can slide on said rods.

The space 0 within the inner wall 2 forms a carburcting chainber, andair is, by means to be presently described, supplied to said Chamber bya pipe 10, leading to a suitable height, centrally Tithin theearbureting Chamber 9, and discharging at the top into a tube 11 closedat the top and carried'by an annular float 12. rl`he air passing down onthe outside of the pipe 10 and on the inside of the tube 11 escapes atthe bottom of said tube 11 by a thin cylindrical Chamber 13 toupstanding pipes lil, each of which diseharges upwardly within thebottom of a, evlindrieal conduit Across each conduit are arranged asuitable number of transverse horizontal tine wire screens 10. The

purpose of these screens is to minutely divide the air, so that, inpassing through the oil, it may be thoroughly impregnated with the oilvapor. The air thus passing through said sereens eventually becomessaturated with oil vapor, so that it rises to the top of the receivercompletely carbureted. This carbureted air is withdrawn from thereceiver by means of a pipe 17 leading` fromV a point above the waterlevel to the gas main of the house or other place where it is to beused. From the bottom of the carbureting chamberapipe 18 leads to aglass gage 19 for indicating the level of the oil therein, a fillingpipe 20 leading upward from the top of said gage and having a funnel 21at the top, and a valve 22 therein.

F or the purpose of obtaining the necessary air pressure for forcing theair through the oil, I provide the apparatus shown on the leftiof Fig.1, which comprises a base 27 upon which are erected inner and outerwalls 28, 29, the space 30 between said walls being filled to a properlevel with water. loto said space 30 depend inner and outer shells 31,32, depending from aV top of an annular air bell or receiver 38. rl`hetop of said air receiver is provided with guides 341 which slide uponguide rods Secured to the outer wall. The air enters said receiver atthe top through a check valve 86 controlled by a spring 87, anddischarges by means of a pipe 88 extending upward through the base to aheight above the level of the water, the bottom of said pipe being` cnneeted by a pipe 89 through a check valve L10 with the pipe 10. lt willthus enter the pipe 10 by means'of said check valve L10, whichimmediately closes on again raising the air receiver.

ln order to avoid the neccssity of raising the air receiver by hand, Iprovide a Water cylinder 41 in which reciprocates a piston 42v having apiston rod 413, which moves through the upper head of the cylinder andhas a head 441 abutting against the top of the air receiver. Surroundingthe cylinder 41 at a short distance is a casing 45, spaced at the bottomfrom said cylinder to allow of the escape of air the upper head of thecylinder being also formed with air` vents 10, so th at as the pistonrises, air can escape through said vents, then in the space between thecylinder fll and casing 415 and then outI at the bottom. lToauton'iatically supply water to said cylinder to raise the hell.,provide an inlet pipe 49 which leads to a three-way valve 48 connectedwith an outlet pipe 47, and also with a supply pipe 50 leading to theinterior of the cylinder 41.

One of the guides 8 secured on the top of the receiver of the carbureteris extended to form a finger 51 and through said finger passes a rod 52.djustably Secured thereon is a stop 58, and said rod is attached to oneend of atrip lever 54 pivoted on a suitable fulorum 55 upon a cross bar56 supported at its ends upon vertical guide rods Secured to the sidesof the outer wall 29 of the air receiver. The other end of said triplever carries a weight 57 to balance the weight of the part upon theoperating Side of the fulcrum. Extending from the side of the lever f-lis a plate 58, which, when the lever descends, is adapted to engage thenose 59 of a hook 60 pivoted at 61 upon the top of the receiver. Saidhook is adapted, when the receiver is raised to pass over a Stud 69,extending from said cross bar 56 and is moved into engagement therewithby means of a spring 63 attached to said hook and to the top of thereceiver. But, when said trip lever descends, said trip plate 58,engaging said nose, pushes it out of engagement with said stud 62, sothat the receiver is free to fall, which it does, forcing the air intothe oil receiver, and thus carbureting the air.

One of said guides 341: attached to the top of the air receiver isextended to form a finger 66, through which passes a movable verticalrod 67 having upper and lower f stops 68, 69, and when, in the descentof the air receiver, said finger strikes the lower stop 69, it causessaid movable vertical rod to descend. The lower end of said rod isloosely connected, as shown at 70, to a lever 71, which is connected bya link 72 with a lever 73 attached to a three-way valve 48, having abalance weight 75. The result is, that, when the rod descends, saidvalve 48 is turned, to cause water to pass into the cylinder Lil fromthe pipe 49, raising the cylinder, and the air receiver. lVhen thelatter arrives at a predetermined height, the finger 66 impinges againstthe upper stop 68, raises the rod 67 and thus turns the three-way valve,to allow the water to escape from the cylinder into the pipe 47, so thatthe air receiver can descend to force the air into the carburetingChamber.

The object of supporting the screen-carrying conduits by means of afloat is to insure uniformity in the thickness of the body of oilthrough which the air passes, thereby also insuring uniformity in' thedegree to which the air is carbureted. lVith this object it is importantthat the fioat should be a sealed or closed float, in order that it maybe of Constant buoyancy, so as to always fiow at a Constant depth.beneath the Surface of the oil. It is also important that the conduitswhich carry the screens should be open at their lower ends for theadmission of oil independently of the admission of air. This is obtainedby supporting the lower ends of the conduits by posts upon the float,and providing comparatively narrow air inletpipes lfl. These pipes,being of much less diameter than the carbureting conduits, produce theresult that the force of the air completely eXpels the oil from the pipeand produces an upward movement of the oil around the pipe and throughthe open lower end of the conduit.

The reason for spacing the carbureting conduits from each other and fromthe wall of the carbureting chamber, is that, thereby, the air emergingfrom the conduits is compelled to flow through the oil above the upperends of the conduits, and cannot escape by Iiowing upward in contactwith the wall of the carbureting Chamber. In each ,arbureting conduit,the screens are arranged at a distance from each other considerably lessthan the diameter of the screens themselves. This arrangement renders itimpossible for the air, after passing through a lower screen, to fiow tothe next screen above along the inner surface of the wall of theconduit, and thus av'oid being carbureted.

I claim 1. In a carbureter, the combination of a carbureting chamber,means for supplying oil thereto, a completely closed hollow fioat, acarbureting conduit supported upon said float, a vertical series ofscreens arranged transversely across said conduit, and means forinjecting air into the lower end of said conduit, substantially asdescribed.
